Hono RPC Client: add option for response parsing

[jansepke]

What is the feature you are proposing?

It would be great if the options of the hc() would allow to add a custom response parser to centralize common code that we want to be executed on every response, e.g.:

const client = hc<AppType>('', {
  handleResponse: async (res) => {
    if (!res.ok) throw Error("error")

   return await res.json()
  }
});

our current solution is to wrap every client call with a custom method that checks for errors and converts to json, e.g.
parseResponse(await client.myEndpoint.$get())

Would it be feasible to implement this as it will likely complicate typing the client methods?

If you just need the handling of !response.ok, then this is what I am doing:

const client = hc<AppType>('', {
  fetch: async (...args: Parameters<typeof fetch>) => {
    const response = await fetch(...args);
    if (!response.ok) throw new Error('Response not OK');
    return response;
  }
});

But there should be dedicated functionality for this so we can modify the response like you are doing and keep everything typesafe.
